[ALSA] Set default index of modem and bt87x drivers to -2

Documentation,ATIIXP-modem driver,BT87x driver,Intel8x0-modem driver
VIA82xx-modem driver
Set the default index value of modem and bt87x drivers to -2 so that
the first slot is excluded when no index option is given.
This gives other uadio drivers a chance to put them as the primary
driver.
